After releasing the new macOS Catalina or any other Mac operating system, I sometimes prefer a clean install of the latest operating system on my iMac / MacBook / MacBook Pro or Mac Pro.
I back up all of the current user home folders on external storage, such as an external hard disk or solid-state drive.
Once the operating system is installed on ‘Macintosh HD’ and an admin user account is created on Mac, it’s time to start transferring data from the external drive to Mac’s user home folder.
Once you have an account setup, follow these steps to transfer music.

I know it happened to me when I purchased a new TP-Links router. But after setting up the router with my ISP (Internet Service Provider), my Mac / iMac / MacBook / MacBook Pro / MacBook Air / Mac Mini started dropping connection intermittently every 5 minutes or every 2 minutes.
After trying everything, here is a list of settings I used to get a stable connection from my router to my Mac.
Step 01: Sign in to your Router’s Admin Page
Step 02: Navigate to Wireless or Advanced > Wireless > Wireless Settings

Cloudflare is a good web service that provides CDN, Caching, HTML – JavaScript – CSS Minifying and security from DDOS attacks free of cost.
However, you must add your domain to Cloudflare to use this service.
Interaction is simple. At the top of your dashboard’s navigation bar, there is a prominent button called ‘Add Site’. Clicking it transfers you to the next page, where you can copy-paste your website’s URL.
If you are getting an error like ‘Invalid Domain’ while adding your website to Cloudflare, use this trick to bypass this error.
If you are copy-pasting the URL with the http suffix, then you will get an error:
// You will get error
http://yourdomain.com
Then you have to enter your domain without http or www, and It should look like this:
// Success
yourdomain.com
The ‘Invalid Domain’ error should be resolved by now.
